PERFORMANCE OPTIMIZATION UNDER A VIRTUALIZED ENVIRONMENT

Argha Roy

Virtualization technology has found a renewed interest owing to the need for cost-efficient operations, better manageability and increased availability of systems. The increased use of physical resources introduces new bottlenecks in performance. This paper proposes methods trying to eliminate these bottlenecks and achieve close to native performance for various guest OS. Here we try to address the following two performance aspects –1. Additional I/O bottlenecks introduced due to virtualization 2. LIVE MIGRARTION support for each virtual machine to ensure maximum uptime
